The Design:

• We have created a detailed design of our final product that addresses the issue of pocket hematoma formation at CIED sites.
• We have created 2D and 3D sketches of our design
• Our design is a one shoulder vest which compresses the chest following the implantation of a cardiac device. 
• The device will have an inflatable air pocket inside the vest directly over the implantation side that can provide custom compression to the affected area, the level of compression being given by a medical professional. 
• The Material of the vest is a heavy duty knit elastic fabric that will be the home to the inflatable airbag. Elastic adjustable straps will hold the vest together. 
• This design solves the issue of overcompression, as the amount of pressure applied to the affected area can be changed according to the patient’s needs.
• While our design cannot guarantee pocket hematoma prevention, it can decrease the risk of a patient developing this critical and dangerous condition.
